This digitized snowflake placemat project is for all computerized long arm systems, and is designed at 12 inches tall x 16.5 inches wide (30.5 cm x 41.9 cm). For best appearance, the placemat should be stitched out at 14 spi. These are great stitched out on seasonal fabric, or left white to use as coloring placemats for kids/grandkids using washable fabric markers!
